NSX Edge NAT reports invalid configuration when multiple ports are used on the Load Balancer configuration (2149942)

  • 0 Ratings

Symptoms

  • NSX Edge NAT reports invalid configuration when multiple ports are used on the Load Balancer configuration
  • You see the error:

    [Nat] Invalid NAT translated port parameter 80,81,82,83. Translated port must be an integer between 1 to 65535, or any

    Where the ports 80,81,82,83 match to a port list configured as a Virtual Server in the Load Balancing section of the Edge

Cause

This issue occurs every time you configure a Load Balancer virtual server with more than one port. Due to this, NAT becomes unmanageable while this configuration state exist for the affected Edge.

Resolution

This is a known issue affecting VMware NSX for vSphere 6.3.x.

Currently, there is no resolution.

To work around this issue:
  1. Remove the multi port mappings from the Load Balancer virtual server temporarily.
  2. Make the necessary modifications to NAT.
  3. Re-add the multi port mappings to the Load Balancer virtual server.
